Transposition tower

A Verdrillmast is in the electrical industry a Abspannmast, in which the outer conductor of a circuit on the pole change place ( twisting ). Such a twist worth for overhead lines from 110 kV that are longer than 20 km. The twist according to a certain scheme, the Verdrillschema.

The twisting is necessary because a capacitance is formed between the conductor and the ground, the line losses caused. Further away from the ground conductors form a lower capacity than later suspended conductor. By twisting one attempts per phase to keep these capacities are the same. Also, interactions between the same conductors and adjacent line systems (eg 16.7 Hz railway power line ) like this.

A twist can also be done in the span, but this is not implemented in Germany. An example of a twist in the tension field is located in Lund in Sweden ( 55 ° 41 ' 47 " N, 13 ° 6' 45 " O55.69638888888913.1125 ).
